He discusses the use of statistical distributions to model real-world phenomena and make probabilistic predictions.
Hypothesis Testing
Hypothesis testing is a fundamental statistical procedure used to determine whether a particular hypothesis about a population is supported by the available data. Freund explains the principles of hypothesis testing, including the null and alternative hypotheses, type I and type II errors, and the concept of statistical significance.
Regression Analysis
Regression analysis is a powerful statistical technique used to investigate the relationship between a dependent variable and one or more independent variables. Freund introduces the concepts of simple and multiple regression, discusses the assumptions and limitations of regression models, and provides step-by-step procedures for conducting regression analyses.
